4. Services

These are key services we are using or have added to the base system:

Service

user id

init.d script

log files location

sshblack

root

sshblack

/var/log/sshblacklisting

postfix

root, postfix

postfix

/var/log/maillog

dsmcad

root

dsmcad-init

/var/log/dsmerror.log, /var/log/dsmsched.log, /var/log/dsmwebcl.log

httpd

apache

httpd

/var/log/httpd/* or /etc/httpd/log/*

tomcat

tomcat

tomcat

/opt/apache-tomcat/apache-tomcat-5.5.16/logs/*

shibd

root

shibd

/var/log/shibboleth/shibd.log

shibboleth IdP

(tomcat app)

(n/a)

/opt/shibboleth-idp/logs/*

shibboleth AA

(tomcat app)

(n/a)

/var/log/shibboleth/transaction.log ??

shibboleth SP

(httpd module)

(n/a)

/var/log/shibboleth/ ??

Of these services, the only one which consumes considerable system runtime resources appears is tomcat. After starting up, serving a single request each for (a) the sakai portal homepage, (b) a remote SP login with AA access and (c) local login via local IdP, tomcat uses 1915M of virtual memory, but only 4.10 minutes of cpu (much of the cpu is spent initialising sakai). The machine has 514M of physical main RAM.

Notes for Redhat and similar systems:

5. Activating additional services

5.1. Automatic backup scheduler

Here are the commands used to activiate the Tivoli client acceptor daemon (CAD), which checks for and initiates automatically scheduled system backups using TSM (aka DSM):

[root@sakai-vre-demo bin]# cp /opt/tivoli/tsm/client/ba/bin/dsmcad-init /etc/init.d
[root@sakai-vre-demo bin]# cd /etc/init.d
[root@sakai-vre-demo init.d]# chmod a+x dsmcad-init 
[root@sakai-vre-demo init.d]# chkconfig --add dsmcad-init
[root@sakai-vre-demo init.d]# chkconfig --list dsmcad-init
dsmcad-init     0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@sakai-vre-demo init.d]# service dsmcad-init start
Starting TSM Scheduler (dsmcad)...done.

5.2. Postfix mail transfer agent

[root@sakai-vre-demo ~]# chkconfig --add postfix
[root@sakai-vre-demo ~]# chkconfig --list postfix
postfix         0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@sakai-vre-demo ~]# service postfix start
Starting postfix: [  OK  ]
